Should I add marco in kernel include/uapi/linux/virtio_gpu.h?

They are used at VIRGL_RENDERER_UNSTABLE_APIS in virglrender.

enum virgl_renderer_capset {
   VIRGL_RENDERER_CAPSET_VIRGL                   = 1,
   VIRGL_RENDERER_CAPSET_VIRGL2                  = 2,
   /* 3 is reserved for gfxstream */
   VIRGL_RENDERER_CAPSET_VENUS                   = 4,
   /* 5 is reserved for cross-domain */
   VIRGL_RENDERER_CAPSET_DRM                     = 6,
};

Thanks,
Ray
